Abstract

The invention relates to a transversal flux machine having a stator (13) and an external rotor (16) disposed about the stator (13), the stator (13) comprising two axial end faces (273, 276), having an inner core (107) of the stator (13), having a cooling path disposed radially within the inner core (107), characterized in that a cooling path either a) protrudes out of the transversal flux machine (10)on the axial end face (273) of the stator (13), wherein said transversal flux machine faces away from an inlet side (303), or b) the cooling path protrudes out of the transversal flux machine (10) on the axial end face (273) of the stator (13), wherein said transversal flux machine faces away from the inlet side, and wherein the cooling path runs between the inlet and the outlet in an intermediate space (265) between the stator (13) and the external rotor (16). of the stator (13) facing the inlet side, wherein the cooling path between the inlet and the outlet runs in an intermediate space (265) between the stator (13) and the external rotor (16).
